Materials with known 37Cl/35Cl isotopic composition
Unit Size: 2.0 g
ISL-354 is pure sodium chloride produced from seawater by Dr. Y. Xiao of the Quinghai Institute of Salt Lakes, Chinese Academy of Sciences, P. R. China [1]. ISL-354 is intended to be used in addition to NIST-SRM-975a sodium chloride as secondary reference material to span part of the range of the natural chlorine isotopic variability.
